Friends, I would like to know if it is possible to import the lets encrypt certificate from an old installation. I did that, but when I update something in Sites, ISPConfig rewrites the apache file and erases the certificate path. I need this, because of several attempts to generate certificate, Lets encrypt does not allow me to generate certificates for this domain for a week. I'm currently using: Debian 11, Apache2
What you can do is disable let's encrypt for that website, and then insert the old SSL cert and key on the SSL tab of the site. But this makes only sense if the cert is still valid for some time.
It is best to troubleshoot the problem by following ISPConfig LE FAQ thread instead, rather than using old LE certs.
